Diaper and Formula Cost Guide
Diapers and feeding are two of the most common monthly baby expenses. They are also easy to underestimate because the cost repeats every month during the first year.
Diaper costs to plan for
Newborns often use more diapers per day than older babies. Your monthly cost depends on diaper brand, package size, sales, subscriptions, and whether you use disposable or cloth diapers.
| Diaper item | Budget note |
|---|---|
| Disposable diapers | Plan for a recurring monthly cost, especially in the first months. |
| Wipes | Wipes are small purchases, but they add up over the year. |
| Diaper cream | Keep a small monthly amount for creams and changing supplies. |
| Cloth diapers | May have higher upfront costs and lower recurring costs, depending on laundry needs. |
Formula and feeding costs
Formula costs vary widely by brand, type, and how much your baby needs. Families who mostly breastfeed may still want to budget for bottles, pump parts, nursing supplies, storage bags, or occasional formula.
| Feeding item | Budget note |
|---|---|
| Formula | Can become one of the largest monthly costs if used often. |
| Bottles and nipples | Some parts need replacement as your baby grows. |
| Nursing supplies | May include pads, storage bags, pump parts, and comfort items. |
| Baby food | Usually becomes more relevant later in the first year. |
Ways to keep costs manageable
Compare unit prices, use subscriptions carefully, watch for sales, and avoid overbuying one diaper size too far ahead. Babies can grow quickly, and unused sizes may not fit later.
For formula, compare prices by ounce, ask your pediatrician before switching types, and check whether your store brand or subscription option makes sense for your baby.
Add it to your baby budget
Once you have a realistic monthly diaper and feeding estimate, add those numbers to the calculator. This makes your first-year total more useful than a generic average.
